When viewing the Directory Source status you are essentially viewing
the status of the connector associated with that Directory Source.

Click Update to refresh the information on this tab. The following information
is provided on the Status tab:

State: Reflects the current state
of the directory source. Valid states include:

Uninstalled: The connector
has not been installed.

Installed: The connector
is installed, but is not ready for synchronization because it has not received
its runtime configuration yet. If the connector remains in this state for
more than a minute, something is probably wrong.

Ready: The connector is
ready for synchronization, but it is currently not synchronizing any objects.
A connector remains in the Ready state if synchronization has not been started
or if synchronization has been started but not all subcomponents have established
connections with the connectors.

Syncing: The connector
is synchronizing objects. There might still be errors, so consult the error
log if you notice that changes are not synchronized.

Active: Indicates whether
the directory source is active or down.

Last Communication: Indicates
the time of the last response from this directory source’s
connector.
